Liberty City Stories - PS2
Unfortunately, the PS2 version has no multiplayer functions

Liberty City Stories - PSP
LCS supports up to 6 player Ad-hoc multiplayer (you basically have to be in the same room as your opponent, no internet play). All players need the game, there is no game sharing feature (yourpsp.com is wrong).

If the ping/latency to your opponent is over 20ms (the limit may be even lower) then LCS will just disconnect you. This means that it's highly unlikely that you will be able to play it on the internet using a tunnelling program like Xlink Kai because 99% of people just can't get a ping that low to anyone, let alone the few people that would be trying to tunnel LCS at the time you want to play. If you were actually able to get a ping that low to someone, you and your opponent also currently need a Linksys router with custom firmware installed. I wish it could be played on the internet but it's just totally impractical.

Liberty City Survivor

The first player to reach the Kill Limit or have the most kills when the Time Limit has been reached wins the game. Killing another player earns you a point but kill yourself and a point will be deducted. Or team up and kill the opposing gang members. The first gang to reach the Kill Limit or have the most kills when the Time Limit has been reached wins the game.

Protection Racket

Would you protect it with your life and some obvious military power? Now you have the chance to prove your commitment, but not just to one beauty but to four sparkling limos.

Destroy four limos at the opposing gang's base. Defend the four limos at your base from incoming Attackers. The game is played in two rounds. Each gang will automatically be assigned in the Defending or Attacking roles. A timer displayed onscreen will measure the time it takes for the Attacking gang to destroy the limos in the first round. Once all four limos in the Defenders’ base have been destroyed, the roles of the Attacking & Defending gang will switch and the second round will begin. The time it took for the limos to be destroyed the first round will now be displayed onscreen and will be counting down. The new Attacking gang must now destroy the limos within this time limit or the other gang will win the game.

Get Stretch

Today you desire your friend’s shiny new car, unfortunately they also desire yours.

Each gang must steal their opposing gang’s car and return it to their own base while protecting their own gang car from being stolen. You can return your own gang car by driving it back to base or by destroying it. Your gang car will automatically be returned to your base after a short period of time if it is unattended by the opposing gang. You must have both gang cars on your base to enable a successful capture. The first gang to reach the Score Limit or make the most captures within the Time Limit wins the game.

The Hit List

Kill the Marked player as quickly as possible. Survive as long as possible when you are the Mark. In the first round, one player will be chosen randomly as the Mark, all other players must try to kill the Marked player as quickly as possible. Once a Marked player has been killed, a different player will be randomly chosen to be the Mark. Making a successful kill on a Marked player will award you with extra time that is added to your survival time at the end of the game. Once all players have been Marked and killed, the player with the longest survival time wins. The Marked player's vehicle will take damage over time.

Street Rage

Players must drive through the checkpoints to get to the finish line first. Players are allowed to change vehicles and shoot other players to win the race. Players will be automatically re-spawned in a vehicle on the track after a short period of time if they do not have a vehicle or if they have been killed. The player that finishes the race first wins. Sticky Tires - Improves vehicle handling for limited time. Instant Repair - Instantly repairs vehicle.

The Wedding List

This is a free-for-all game where players must collect cars scattered throughout the city and deliver them to shipping crates. Only players in the vehicles to be collected will know the destinations of the shipping crates. Cash is awarded based on the condition of the cars when they are delivered. Once all the cars have been collected and delivered, the player with the most cash wins this game mode.

Tanks for the memories

Be the first to the tank and try to survive the target Tank Time. Other players must try to destroy your tank before the Tank Time is reached. If this happens the player who caused the most damage to the tank will now occupy the new tank and you must destroy it as quickly as possible. First player that hits the Tank Time wins!
